Session 1 Tp 1

  1. 1. Microsoft Windows Server 2003 Network Infrastructure – Planning and Maintenance/ Session 1 / Slide 1 of 21 Session 1 Planning a Network Service Infrastructure
  2. 2. Microsoft Windows Server 2003 Network Infrastructure – Planning and Maintenance/ Session 1 / Slide 2 of 21 Objectives  Explain Network Services Infrastructure design  Identify the protocols for the Network Infrastructure design  Identify the Data-Link layer protocol  Discuss the Networking services  Analyze the Organizational goals
  3. 3. Microsoft Windows Server 2003 Network Infrastructure – Planning and Maintenance/ Session 1 / Slide 3 of 21 Network Infrastructure  Network Infrastructure consists of:  Physical infrastructure: Provides the basic design of the network  Logical infrastructure: Consists of the software elements that connect, maintain, and provide security to the hosts on the network
  4. 4. Microsoft Windows Server 2003 Network Infrastructure – Planning and Maintenance/ Session 1 / Slide 4 of 21 Network Services Infrastructure Stages  Steps in designing a Network Services Infrastructure are:  Plan  Implement  Maintain Networking Services Infrastructur e Implement Plan Maintain
  5. 5. Microsoft Windows Server 2003 Network Infrastructure – Planning and Maintenance/ Session 1 / Slide 5 of 21 Selecting the Protocols for the Network  The Open Systems Interconnection (OSI) reference model defines a networking framework for implementing protocols such as TCP/IP and Ethernet
  6. 6. Microsoft Windows Server 2003 Network Infrastructure – Planning and Maintenance/ Session 1 / Slide 6 of 21 Selecting the Protocols for the Network Contd…  Physical layer (layer 1) – Specifies the signals transmitted over the network  Data-Link layer (layer 2) – Furnishes transmission protocol knowledge, management and handles errors in the Physical layer  Network layer (layer 3) – Defines the functions that provide communication between computers on different networks
  7. 7. Microsoft Windows Server 2003 Network Infrastructure – Planning and Maintenance/ Session 1 / Slide 7 of 21 Selecting the Protocols for the Network Contd…  Transport layer (layer 4) – Guarantees data delivery and ensures error detection  Session layer (layer 5) – Establishes, maintains and ceases connections between applications  Presentation layer (layer 6) – Translates the computer syntax into a readable format  Application layer (layer 7) – Supports application and end-user processes
  8. 8. Microsoft Windows Server 2003 Network Infrastructure – Planning and Maintenance/ Session 1 / Slide 8 of 21 Data-Link Layer Protocol  We must consider the following criteria while selecting the Data-Link layer protocol:  Type of Media  Transmission speed  The most widely used Data-Link layer protocol is the Ethernet
  9. 9. Microsoft Windows Server 2003 Network Infrastructure – Planning and Maintenance/ Session 1 / Slide 9 of 21 Types of Media  Local Area Networks are developed using:  Unshielded Twisted Pair (UTP) Transmission Media  Fiber Optic  Wireless Networking
  10. 10. Microsoft Windows Server 2003 Network Infrastructure – Planning and Maintenance/ Session 1 / Slide 10 of 21 Transport Layer Protocol  Windows Server 2003 supports three transport layer protocols such as:  Transmission Control Protocol/Internet Protocol (TCP/IP)  Internetwork Packet Exchange (IPX)  NetBEUI
  11. 11. Microsoft Windows Server 2003 Network Infrastructure – Planning and Maintenance/ Session 1 / Slide 11 of 21 TCP/IP  Communicates using the IP (Internet Protocol), TCP (Transmission Control Protocol) and UDP (User Datagram Protocol) protocols
  12. 12. Microsoft Windows Server 2003 Network Infrastructure – Planning and Maintenance/ Session 1 / Slide 12 of 21 IPX  Communicates using the following protocols:  Sequenced Packet Exchange (SPX) – Connection-oriented transport layer protocol  NetWare Core Protocol (NCP) – Equivalent of UDP
  13. 13. Microsoft Windows Server 2003 Network Infrastructure – Planning and Maintenance/ Session 1 / Slide 13 of 21 NetBEUI  Uses the NetBIOS namespace to identify computers on the network  We can install the NetBEUI on Windows Server 2003 computer using the installation files to check network communication problems.
  14. 14. Microsoft Windows Server 2003 Network Infrastructure – Planning and Maintenance/ Session 1 / Slide 14 of 21 Selecting Networking Services  The network design process involves:  Network Foundation  Internet Connectivity  Integrated Design for Networking Services Infrastructure  Remote Access Connectivity
  15. 15. Microsoft Windows Server 2003 Network Infrastructure – Planning and Maintenance/ Session 1 / Slide 15 of 21 Network Foundation  Enables the IP addressing support, automatic client configuration, and services for name resolution  The networking services are:  TCP/IP  DHCP  DNS
  16. 16. Microsoft Windows Server 2003 Network Infrastructure – Planning and Maintenance/ Session 1 / Slide 16 of 21 Internet Connectivity  Enables remote users to access the internal network through the internet without any risk.  The Networking services are:  NAT  Microsoft Proxy Server
  17. 17. Microsoft Windows Server 2003 Network Infrastructure – Planning and Maintenance/ Session 1 / Slide 17 of 21 Connectivity for Remote Access  While designing the Network services infrastructure, we must use the routing services to connect multiple physical segments placed in the same geographical locations
  18. 18. Microsoft Windows Server 2003 Network Infrastructure – Planning and Maintenance/ Session 1 / Slide 18 of 21 Infrastructure design  We must provide the required networking solution to the organization through:  Management Strategy Design  Combination of services  Organizational Network solution
  19. 19. Microsoft Windows Server 2003 Network Infrastructure – Planning and Maintenance/ Session 1 / Slide 19 of 21 Analyzing Organizational Goals  While designing the network services infrastructure we must take the following points into consideration:  Functionality  Security  Availability  Performance
  20. 20. Microsoft Windows Server 2003 Network Infrastructure – Planning and Maintenance/ Session 1 / Slide 20 of 21 Summary  Network Services Infrastructure design depends on the execution of three phases:  Plan  Implement  Maintain  The design process involves:  Network Foundation  Internet Connectivity  Remote Access Connectivity  Infrastructure design
  21. 21. Microsoft Windows Server 2003 Network Infrastructure – Planning and Maintenance/ Session 1 / Slide 21 of 21 Summary Contd…  A Network Infrastructure is made up of the Physical and the Logical infrastructure  The Open Systems Interconnection (OSI) reference model defines a networking framework for implementing protocols  The Data-Link layer protocol is one of the main decisions to be taken while designing the network infrastructure  Common network services include TCP/IP, DHCP, DNS, and WINS  Remote Access Connectivity can be achieved through IP Routing, Routing and Remote Access, and RADIUS
